The Zero Gravity Research Facility at the NASA Glenn Research Center includes a 145 m drop tower.
Question:
The Zero Gravity Research Facility at the NASA Glenn Research Center includes a 145 m drop tower. This is an evacuated vertical tower through which, among other possibilities, a 1 m diameter sphere containing an experimental package can be dropped.
(a) How long is the sphere in free fall?
(b) What is its speed just as it reaches a catching device at the bottom of the tower?
(c) When caught, the sphere experiences an average deceleration of 255 as its speed is reduced to zero. Through what distance does it travel during the deceleration?
Step by Step Answer:
There is no air resistance which makes it quite accurate to set a g 98 ms where downward is the y di...View the full answer

Take 2 forks and place them on one another in such a way that we can place the coin in between the prongs. Now try to place the coin with forks on the edge of the glass. It will take you some time to adjust the coin on the edge. This requires a little practice to adjust the coin on the edge of the glass. With a little effort, we will see the coin sitting on the edge calmly. If you look closely you will see it wobbling a little bit. The mass is in the handles of the forks so as a low center of mass it stables as it looks.
